In theory, the sortArrow will show if the dataProvider has a valid sort property with a single sortField that describes the sorted column. If you did a more complex sort, you might be better off drawing custom header renderers that better depicts the complex sort.

Has anyone done this? Hi there I tried exactly that in various different ways, but wasnt able to get it to work. I have an array, which I convert to an array collection, on which I sort and refresh, after which I set as a dataProvider for my DataGrid. Still no sort arrow is shown. I then tried extending the DataGrid class, but that opened up another can of worms Help, anyone??
